ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2024; 4:e137. [PMID: 39346664 PMCID: PMC11428003 DOI: 10.1017/ash.2024.350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 05/01/2024] [Accepted: 05/03/2024] [Indexed: 10/01/2024]
Abstract
Objective Contact precautions for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) have limited data on efficacy and have been associated with patient harm. Still, a 2015 Society for Healthcare Epidemiology of America (SHEA) Research Network (SRN) survey showed only 7% of hospitals discontinued routine MRSA/VRE contact precautions. The study objectives were to identify the current proportion of hospitals that have discontinued routine MRSA/VRE contact precautions and motivations for change. Design An online survey was conducted of the SRN on current use and views of contact precautions for MRSA/VRE in each facility. An initial survey followed by 2 reminders was sent between 5/18/2021 and 6/9/2021. Participants SRN facilities. Results The response rate was 43% (37/87) of facilities surveyed and 35% of respondents were not routinely using contact precautions for MRSA and VRE. The most frequently reported reason for discontinuing contact precautions was research on the safety of discontinuing contact precautions without an increase in healthcare-associated infections (reported for 92% of facilities for MRSA and 100% for VRE). Of those using contact precautions, the most frequently reported reason to continue was a lack of safety data for discontinuation (MRSA 58% and VRE 46%). Most of those continuing contact precautions were interested in using contact precautions differently in their facility (MRSA 63% and VRE 58%). Conclusions Over one in three healthcare facilities surveyed do not use contact precautions for MRSA or VRE. Most facilities choosing to continue contact precautions are interested in a different implementation strategy.

Pan H, Zhang C, Song J, Yang R, Zhang Z. Does the removal of isolation for VRE-infected patients change the incidence of health care-associated VRE?: A systematic review and meta-analysis. Am J Infect Control 2024:S0196-6553(24)00633-3. [PMID: 39111343 DOI: 10.1016/j.ajic.2024.07.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Revised: 07/27/2024] [Accepted: 07/27/2024] [Indexed: 08/21/2024]
Abstract
BACKGROUND Several single-center studies have suggested that eliminating isolation for vancomycin-resistant enterococci (VRE) control in the context of endemic or nonoutbreak settings, has no impact on infection rates. We performed a systematic review and meta-analysis on the impact of discontinuing isolation. METHODS We searched PubMed, Embase, the Cochrane Library, and Web of Science through April 10, 2024 for studies evaluating discontinuation of isolation for VRE. Subgroup analyses assessed sources of heterogeneity. RESULTS Nine studies were included in the final review. Four reported the incidence of hospital-acquired VRE (HA-VRE) infections and 5 reported the incidence of hospital-acquired VRE bloodstream infections (HA-VRE BSI). No significant difference between the rates of HA-VRE infection before and after stopping isolation was observed (risk ratios, 0.93; 95% confidence interval, 0.68-1.26; P = .62), as well as no significant difference on the incidence of HA-VRE BSI (risk ratios, 0.68; 95% confidence interval, 0.44-1.07, P = .09). Furthermore, we conducted 2 subgroup analyses: one stratified by whether the studies were conducted during Coronavirus Disease 19 (COVID-19), and the other stratified by whether clinicians continued to use personal protective equipment. Both analyses revealed no significant differences in the incidence of HA-VRE BSI and termination of isolation between the subgroups. CONCLUSIONS In the context of endemic or nonoutbreak settings, discontinuation of isolation for VRE patients has not been associated with an increased rate of HA-VRE infections.

Abstract
PURPOSE OF REVIEW Healthcare-associated infections (HAIs) represent a major burden on healthcare facilities. Effective infection prevention strategies are essential to prevent the spread of HAIs. These can be broadly classified as vertical and horizontal interventions. Through this review, we aim to assess the merits of these strategies. RECENT FINDINGS Vertical strategies include active surveillance testing and isolation for patients infected or colonized with a particular organism. These strategies are beneficial to curb the spread of emerging pathogens and during outbreaks. However, the routine use of contact precautions for organisms such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus remains controversial. Horizontal interventions are larger-scale and reduce HAIs by targeting a common mode of transmission shared by multiple organisms. Among these, hand hygiene, chlorhexidine gluconate bathing of select patients and environmental decontamination are the most high-yield and must be incorporated into infection prevention programs. As antimicrobial stewardship is also an effective horizontal strategy, antimicrobial stewardship programs must operate in synergy with infection prevention programs for maximal impact. SUMMARY Overall, horizontal interventions are considered more cost-effective and have a broader impact. Infection control programs may opt for a combination of vertical and horizontal strategies based on local epidemiology and available resources.

Abstract
PURPOSE OF REVIEW This review covers recent research regarding the challenges posed by climate change within the areas of antimicrobial stewardship and infection prevention, and ways to build resiliency in these fields. RECENT FINDINGS Infectious disease patterns are changing as microbes adapt to climate change and changing environmental factors. Capacity for testing and treating infectious diseases is challenged by newly emerging diseases, which exacerbate challenges to antimicrobial stewardship and infection prevention.Antimicrobial resistance is accelerated due to environmental factors including air pollution, plastic pollution, and chemicals used in food systems, which are all impacted by climate change.Climate change places infection prevention practices at risk in many ways including from major weather events, increased risk of epidemics, and societal disruptions causing conditions that can overwhelm health systems. Researchers are building resilience by advancing rapid diagnostics and disease modeling, and identifying highly reliable versus low efficiency interventions. SUMMARY Climate change and associated major weather and socioeconomic events will place significant strain on healthcare facilities. Work being done to advance rapid diagnostics, build supply chain resilience, improve predictive disease modeling and surveillance, and identify high reliability versus low yield interventions will help build resiliency in antimicrobial stewardship and infection prevention for escalating challenges due to climate change.

Implementation of contact precautions for multidrug-resistant organisms in the post-COVID-19 pandemic era: An updated national Emerging Infections Network (EIN) survey. Infect Control Hosp Epidemiol 2024; 45:703-708. [PMID: 38351872 PMCID: PMC11102826 DOI: 10.1017/ice.2024.11] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 12/14/2023] [Accepted: 01/03/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVE To understand how healthcare facilities employ contact precautions for patients with multidrug-resistant organisms (MDROs) in the post-coronavirus disease 2019 (COVID-19) era and explore changes since 2014. DESIGN Cross-sectional survey. PARTICIPANTS Emerging Infections Network (EIN) physicians involved in infection prevention or hospital epidemiology. METHODS In September 2022, we sent via email an 8-question survey on contact precautions and adjunctive measures to reduce MDRO transmission in inpatient facilities. We also asked about changes since the COVID-19 pandemic. We used descriptive statistics to summarize data and compared results to a similar survey administered in 2014. RESULTS Of 708 EIN members, 283 (40%) responded to the survey and 201 reported working in infection prevention. A majority of facilities (66% and 69%) routinely use contact precautions for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) respectively, compared to 93% and 92% in 2014. Nearly all (>90%) use contact precautions for Candida auris, carbapenem-resistant Enterobacterales (CRE), and carbapenem-resistant Acinetobacter baumannii. More variability was reported for carbapenem-resistant Pseudomonas aeruginosa and extended-spectrum β-lactamase-producing gram-negative organisms. Compared to 2014, fewer hospitals perform active surveillance for MRSA and VRE. Overall, 90% of facilities used chlorhexidine gluconate bathing in all or select inpatients, and 53% used ultraviolet light or hydrogen peroxide vapor disinfection at discharge. Many respondents (44%) reported changes to contact precautions since COVID-19 that remain in place. CONCLUSIONS Heterogeneity exists in the use of transmission-based precautions and adjunctive infection prevention measures aimed at reducing MDRO transmission. This variation reflects a need for updated and specific guidance, as well as further research on the use of contact precautions in healthcare facilities.

The impact of discontinuing single-room isolation of patients with vancomycin-resistant enterococci: a quasi-experimental single-centre study in South Korea. J Hosp Infect 2024; 147:77-82. [PMID: 38492645 DOI: 10.1016/j.jhin.2024.02.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 02/27/2024] [Accepted: 02/28/2024] [Indexed: 03/18/2024]
Abstract
OBJECTIVES There is limited data on the effects of discontinuing single-room isolation while maintaining contact precautions, such as the use of gowns and gloves. In April 2021, our hospital ceased single-room isolation for patients with vancomycin-resistant enterococci (VRE) because of single-room unavailability. This study assessed the impact of this policy by examining the incidence of hospital-acquired VRE bloodstream infections (HA-VRE BSI). METHODS This retrospective quasi-experimental study was conducted at a tertiary-care hospital in Seoul, South Korea. Time-series analysis was used to evaluate HA-VRE BSI incidence at the hospital level and in the haematology unit before (phase 1) and after (phase 2) the policy change. RESULTS At the hospital level, HA-VRE BSI incidence level (VRE BSI per 1000 patient-days per month) and trend did not change significantly between phase 1 and phase 2 (coefficient -0.015, 95% confidence interval (CI): -0.053 to 0.023, P=0.45 and 0.000, 95% CI: -0.002 to 0.002, P=0.84, respectively). Similarly, HA-VRE BSI incidence level and trend in the haematology unit (-0.285, 95% CI: -0.618 to 0.048, P=0.09 and -0.018, 95% CI: -0.036 to 0.000, P = 0.054, respectively) did not change significantly across the two phases. CONCLUSIONS Discontinuing single-room isolation of VRE-colonized or infected patients was not associated with an increase in the incidence of VRE BSI at the hospital level or among high-risk patients in the haematology unit. Horizontal intervention for multi-drug-resistant organisms, including measures such as enhanced hand hygiene and environmental cleaning, may be more effective at preventing VRE transmission.

Abstract
BACKGROUND Many hospitals caring for adult patients have discontinued the requirement for contact precautions (CP) for patients with methicillin-resistant Staphylococcus aureus (MRSA) infection or colonization without reported negative effects. It is not clear whether this experience can be extrapolated to pediatric facilities. METHODS CP for MRSA were discontinued in all locations except the neonatal intensive care unit at a 3-hospital pediatric healthcare system in September 2019. All hospitalized patients underwent surveillance for LabID healthcare facility-onset MRSA infections. Analysis was done using interrupted time series (ITS) from September 2017 through August 2023 and aggregate before-and-after rate ratios. RESULTS There were 234 incident healthcare facility-onset MRSA infections during 766 020 patient days of surveillance. After discontinuation of CP for MRSA there was no change in the ITS slope (0.06, 95% CI: -0.35 to 0.47, P = .78) or intercept (0.21, 95% CI: -0.36 to 0.78, P = .47) of the LabID healthcare facility-onset MRSA infection incidence density rate. Additionally, there was no change in the aggregate incidence density rate of these MRSA LabID events (aggregate rate ratio = 0.98, 95% CI: 0.74 to 1.28). MRSA nasal colonization among patients being screened before cardiac surgery did not change (aggregate rate ratio = 0.94, 95% CI: 0.60 to 1.48). The prevalence rate of contact isolation days decreased by 14.0%. CONCLUSIONS Discontinuation of CP for pediatric patients with MRSA was not associated with increased MRSA infection over 4 years. Our experience supports considering discontinuation of CP for MRSA in similar pediatric healthcare settings in the context of good adherence to horizontal infection prevention measures.

Abstract
BACKGROUND Contact precautions (CPs) have been widely implemented in hospitals, particularly in intensive care units (ICUs), as the standard approach for managing meticillin-resistant Staphylococcus aureus (MRSA). However, the effectiveness of CPs in preventing MRSA transmission remains a subject of debate. AIM To assess the effectiveness of CPs in reducing MRSA transmission within ICUs. METHODS A comprehensive analysis was conducted using data from 16 sets of parameters collected from 13 field studies investigating the effectiveness of CPs in ICUs, and an epidemiologic model was developed to simulate the dynamics of MRSA incidence in the hospital setting. FINDINGS The analysis demonstrated a mean reduction of 20.52% (95% confidence interval -30.52 to 71.60%) in the MRSA transmission rate associated with the implementation of CPs. Furthermore, reducing the time-delay of screening tests and increasing the percentage of patients identified with MRSA through screening at admission were found to contribute to the effectiveness of CPs. CONCLUSION Proper implementation of CPs, with a particular emphasis on early identification of MRSA-colonized/infected patients, demonstrated a strong association with reduced MRSA transmission within the hospital setting. However, further research is necessary to investigate the effectiveness and safety of decolonization and other interventions used in conjunction with CPs to mitigate the risk of infection among colonized patients.

Abstract
Vancomycin-resistant enterococci (VRE) are common causes of bloodstream infections (BSIs) with high morbidity and mortality rates. They are pathogens of global concern with a limited treatment pipeline. Significant challenges exist in the management of VRE BSI, including drug dosing, the emergence of resistance, and the optimal treatment for persistent bacteremia and infective endocarditis. Therapeutic drug monitoring (TDM) for antimicrobial therapy is evolving for VRE-active agents; however, there are significant gaps in the literature for predicting antimicrobial efficacy for VRE BSIs. To date, TDM has the greatest evidence for predicting drug toxicity for the three main VRE-active antimicrobial agents daptomycin, linezolid, and teicoplanin. This article presents an overview of the treatment options for VRE BSIs, the role of antimicrobial dose optimization through TDM in supporting clinical infection management, and challenges and perspectives for the future.

Abstract
BACKGROUND Isolating patients infected or colonized with vancomycin-resistant enterococci (VRE) in a private room or cohort room to prevent hospital transmission is controversial. AIM To evaluate the effect of a relaxed isolation policy for VRE-infected or colonized patients on healthcare-associated (HA) VRE bacteraemia in an acute care hospital with a predominantly shared-room setting. METHODS The incidence of HA VRE bacteraemia was compared during a private isolation era (October 2014-September 2017), a cohort isolation era (October 2017-June 2020), and a no isolation era (July 2020-June 2022). Using Poisson regression modelling, an interrupted time-series analysis was conducted to analyse level changes and trends in incidences of HA VRE bacteraemia for each era. FINDINGS The proportion of VRE-infected or -colonized patients staying in shared rooms increased from 18.3% in the private isolation era to 82.6% in the no isolation era (P < 0.001). There was no significant difference in the incidences of HA VRE bacteraemia between the private isolation era and the cohort isolation era (relative risk: 1.01; 95% confidence interval: 0.52-1.98; P = 0.977) or between the cohort isolation era and the no isolation era (0.99; 0.77-1.26; P = 0.903). In addition, there was no significant slope increase in the incidence of HA VRE bacteraemia between any of the eras. CONCLUSION In a hospital with predominantly shared rooms, the relaxation of isolation policy did not result in increased HA VRE bacteraemia, when other infection control measures were maintained.

Abstract
OBJECTIVE To define conditions in which contact precautions can be safely discontinued for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). DESIGN Interrupted time series. SETTING 15 acute-care hospitals. PARTICIPANTS Inpatients. INTERVENTION Contact precautions for endemic MRSA and VRE were discontinued in 12 intervention hospitals and continued at 3 nonintervention hospitals. Rates of MRSA and VRE healthcare-associated infections (HAIs) were collected for 12 months before and after. Trends in HAI rates were analyzed using Poisson regression. To predict conditions when contact precautions may be safely discontinued, selected baseline hospital characteristics and infection prevention practices were correlated with HAI rate changes, stratified by hospital. RESULTS Aggregated HAI rates from intervention hospitals before and after discontinuation of contact precautions were 0.14 and 0.15 MRSA HAI per 1,000 patient days (P = .74), 0.05 and 0.05 VRE HAI per 1,000 patient days (P = .96), and 0.04 and 0.04 MRSA laboratory-identified (LabID) events per 100 admissions (P = .57). No statistically significant rate changes occurred between intervention and non-intervention hospitals. All successful hospitals had low baseline MRSA and VRE HAI rates and high hand hygiene adherence. We observed no correlations between rate changes after discontinuation and the assessed hospital characteristics and infection prevention factors, but the rate improved with higher proportion of semiprivate rooms (P = .04). CONCLUSIONS Discontinuing contact precautions for MRSA/VRE did not result in increased HAI rates, suggesting that contact precautions can be safely removed from diverse hospitals, including community hospitals and those with lower proportions of private rooms. Good hand hygiene and low baseline HAI rates may be conditions permissive of safe removal of contact precautions.

Abstract
Ventilator-associated pneumonia (VAP) occurs more than 48h after mechanical ventilation and is associated with a high mortality rate. The current hospital-based study aims to investigate the association between VAP rate, incidence of bacteremia from multidrug-resistant (MDR) pathogens, and infection control interventions in a single case mix ICU from 2013 to 2018. Methods: The following monthly indices were analyzed: (1) VAP rate; (2) use of hand hygiene disinfectants; (3) isolation rate of patients with MDR bacteria; and (4) incidence of bacteremia/1000 patient-days (total cases, total carbapenem-resistant cases, and carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae cases separately). Results: Time trends of infection control interventions showed increased rates in isolation of patients with MDR pathogens (p <0.001) and consumption of hand disinfectant solutions (p =0.001). The last four years of the study an annual decrease of VAP rate by 35.12% (95% CI: −53.52 to −9.41; p =0.01) was recorded, which significantly correlated not only with reduced trauma and cardiothoracic surgery patients (IRR:2.49; 95% CI: 2.09−2.96; p <0.001), but also with increased isolation rate of patients with MDR pathogens (IRR: 0.52; 95% CI: 0.27−0.99; p = 0.048), and hand disinfectants use (IRR: 0.40; 95% CI: 0.18−0.89; p =0.024). Conclusions: Infection control interventions significantly contributed to the decrease of VAP rate. Constant infection control stewardship has a stable time-effect and guides evidence-based decisions.

Abstract
IMPORTANCE Although contact isolation has been widely recommended for multidrug-resistant organisms, contact isolation has raised some concerns that it may bring unintended patient harms. OBJECTIVE To compare adverse events between a contact isolation group with vancomycin-resistant Enterococcus (VRE) and a matched comparison group using a relatively large data set from full electronic medical records (EMR) and propensity score-matching methods. DESIGN, SETTING, AND PARTICIPANTS This retrospective, matched cohort study was conducted at Seoul National University Bundang Hospital (SNUBH) in Korea, a tertiary, university-affiliated hospital that has 1337 inpatient beds. Participants included a total of 98 529 hospitalized adult patients (aged ≥18 years) during 2015 to 2017. EXPOSURES Contact isolation in a single or shared double room. MAIN OUTCOMES AND MEASURES As adverse contact isolation-related outcomes, falls and pressure ulcers were included. All relevant EMR data were extracted from the SNUBH clinical data warehouse. Risk factors for adverse events were included in the propensity score model based on literature reviews, such as Braden scale score and Hendrich II fall risk score. A fine stratification and weighting (FSW) and a 1:10 nearest neighbor (NN) propensity score matching as a sensitivity analysis were adopted to compare adverse events between the 2 groups for the observation period from the study entry date and the exit date. Time-to-event analyses with a Cox proportional hazard model were conducted in December 2021. RESULTS For comparison of outcomes in wards, 177 patients (mean [SD] age, 67.38 [14.12] years; 98 [55.4%] female) with VRE and 93 022 patients (mean [SD] age, 56.44 [16.88] years; 49 462 [53.2%] female) without VRE were included and no difference was found in basic characteristics from the FSW (VRE contact isolation [n = 172] vs comparison [n = 69 434]) as well as from the 1:10 NN (VRE contact isolation [n = 168] vs comparison [n = 1650]). Among 177 patients with VRE contact isolation, 8 pressure ulcers and 3 falls occurred during their hospital stays; incidence rates of adverse events were 2.5 and 0.9 per 1000 patient-days, respectively (pressure ulcer incidence rate from the FSW: 2.53 per 1000 patient-days [95% CI, 1.09-4.99 per 1000 patient-days]; pressure ulcer incidence rate from the 1:10 NN: 2.54 per 1000 patient-days [95% CI, 1.10-5.01 per 1000 patient-days]; fall incidence rate from the FSW: 0.87 per 1000 patient-days [95% CI, 0.18-2.54 per 1000 patient-days]; fall incidence rate from the 1:10 NN: 0.87 per 1000 patient-days [95% CI, 0.18-2.55 per 1000 patient-days]). The hazard ratios for adverse events showed no statistically significant differences for both groups: 1.42 (95% CI, 0.67-2.99) for pressure ulcer and 0.66 (95% CI, 0.20-2.13) for fall from the FSW. CONCLUSIONS AND RELEVANCE In this cohort study, no association was found between the likelihood of adverse events and contact isolation using propensity score-matching methods and closely related covariates for adverse events.

Central line-associated bloodstream infections, multidrug-resistant bacteraemias and infection control interventions: a six-year time-series analysis in a tertiary-care hospital in Greece. J Hosp Infect 2022; 123:27-33.

Abstract
BACKGROUND Central line-associated bloodstream infections (CLABSI) are serious healthcare-associated infections with substantial morbidity and hospital costs. AIM To investigate the association between the incidence of CLABSI, the implementation of specific infection control measures, and the incidence of multidrug-resistant (MDR) bacteraemias in a tertiary-care hospital in Greece from 2013-2018. METHODS Analysis was applied for the following monthly calculated indices: 1.CLABSI rate, 2.use of hand hygiene disinfectants, 3.isolation rate of patients with MDR bacteria, 4.incidence of bacteraemias [total resistant Gram-negative: carbapenem-resistant (CR) Acinetobacter baumanii, Pseudomonas aeruginosa, Klebsiella pneumoniae and/or Gram-positive: meticillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci]. FINDINGS Total bacteraemias from CR-Gram-negative pathogens statistically correlated with increased CLABSI rate in total Hospital Departments (IRR: 1.17, 95% CI: 1.05-1.31, p-value: 0.006) and Adults ICU (IRR: 1.37, 95%CI: 1.07-1.75, p-value: 0.013). In Adults ICU, every increase in the incidence of each resistant Gram-negative pathogen significantly correlated with decreased CLABSI rate (CR-A. baumanii: IRR: 0.59, 95%CI: 0.39-0.90, p-value=0.015; CR-K. pneumoniae: IRR: 0.48, 95%CI: 0.25-0.94, p-value=0.031; CR-P. aeruginosa: IRR: 0.54, 95%CI: 0.33-0.89, p-value=0.015). The use of hand disinfectants correlated with decreased CLABSI rate 1-3 months before the application of this intervention, in total Hospital Departments (IRR: 0.80, 95%CI: 0.69-0.93, p-value: 0.005), and for scrub disinfectants the current month in Adults ICU (IRR: 0.34, 95%CI: 0.11-1.03, p-value: 0.057). Isolation of patients with MDR pathogens was not associated with CLABSI incidence. CONCLUSION Hand hygiene was associated with a significant reduction of CLABSI incidence in our hospital. Time-series analysis is an important tool to evaluate infection control interventions.

Abstract
Vancomycin-resistant enterococcus (VRE) is a pathogen of growing concern due to increasing development of antibiotic resistance, increasing length of hospitalizations and excess mortality. The utility of some infection control practices are debatable, as newer developments in infection prevention strategies continued to be discovered. This article summarizes the significance of VRE and VRE transmission, along with highlighting key changes in infection control practices within the past 5 years.

Abstract
IMPORTANCE Visitor contact precautions (VCPs) are commonly used to reduce the transmission of Clostridioides difficile at health care institutions. Implementing VCPs requires considerable personnel and personal protective equipment resources. However, it is unknown whether VCPs are associated with reduced hospital-onset C difficile infection (HO-CDI) rates. OBJECTIVE To estimate the association between VCPs and HO-CDI rates using simulation modeling. DESIGN, SETTING, AND PARTICIPANTS This simulation study, conducted between July 27, 2020, and August 11, 2020, used an established agent-based simulation model of C difficile transmission in a 200-bed acute care adult hospital to estimate the association between VCPs and HO-CDI while varying assumptions about factors such as patient susceptibility, behavior, and C difficile transmission. The model simulated hospital activity for 1 year among a homogeneous, simulated adult population. INTERVENTIONS No VCP use vs ideal use of VCPs under different hospital configurations. MAIN OUTCOMES AND MEASURES The rate of HO-CDI per 10 000 patient-days according to the Centers for Disease Control and Prevention's definition of HO-CDI. RESULTS With use of the simulation model, the baseline rate of HO-CDI was 7.94 10 000 patient-days (95% CI, 7.91-7.98 per 10 000 patient-days) with no VCP use compared with 7.97 per 10 000 patient-days (95% CI, 7.93-8.01 per 10 000 patient-days) with ideal VCP use. Visitor contact precautions were not associated with a reduction of more than 1% in HO-CDI rates in any of the tested scenarios and hospital settings. Independently increasing the hand-hygiene compliance of the average health care worker and environmental cleaning compliance by no more than 2% each was associated with greater HO-CDI reduction compared with all other scenarios, including VCPs. CONCLUSIONS AND RELEVANCE In this simulation study, the association between VCPs and HO-CDI was minimal, but improvements in health care worker hand hygiene and environmental cleaning were associated with greater reductions in estimated HO-CDI. Hospitals may achieve a higher rate of reduction for HO-CDI by focusing on making small improvements in compliance with interventions other than VCP.
